Abstract

The invention provides an antistatic masterbatch, which comprises the following components: 1-15 wt% of alkaline metal salt, 0.1-2 wt% of antioxidant, 0.1-2 wt% of heat stabilizer, 0.01-10 wt% of assistant antistatic agent and 71-95 wt% of high polymer material with polyether blocks. The invention also provides antistatic alloy prepared from the masterbatch, which comprises the following components: 2-8 wt% of antistatic masterbatch, 20-50 wt% of PA66 (Polymide 66), 20-50 wt% of PA6 (Polymide 6), 15-25 wt% of POE (Polyethylene Octene Elastomer) and 1-5 wt% of compatilizer. The invention also provides a preparation method of the masterbatch and a preparation method of the alloy, which respectively comprise the following steps of: mixing the components for 1-10 minutes; discharging; extruding; pelleting; and obtaining the product. The antistatic masterbatch has the surface resistivity being 102-103 ohm m, a lasting antistatic effect, less additive amount, and good compatibility with many kinds of resin. The antistatic alloy has the surface resistivity being 106-108 ohm m, higher comprehensive mechanical property, low cost and good heat resistance.

Description

technical field [0001] The invention relates to the field of antistatic materials, in particular to an antistatic master batch, an alloy material made of the same and a preparation method for the two. Background technique [0002] Due to its good comprehensive mechanical properties, high heat resistance, good wear resistance, self-lubricating properties, good flame retardancy, excellent chemical corrosion resistance, excellent barrier properties and other properties, nylon has become the most suitable for current applications. Wide range of engineering plastics. POE is non-toxic, odorless, low density, low price, and has excellent properties such as aging resistance, ozone resistance, and chemical medium resistance. POE can be used as an impact modifier for engineering plastics, used to make mechanical parts with impact resistance requirements, corrosion-resistant parts, automobiles, electrical parts and other products. Adding POE to nylon can effectively improve its hygro...
